And most of the useable light from CFL's is given off from the sides, not the top. So hang them sideways. You need more light tho. Clamp light at walmart is 10 bucks, splitter maybe two bucks, and 2 more lights from there. Then you can plan on buying more lights/splitters, and clamps if you keep it a CFL grow. I'm doing my first indoor grow with all CFL's right now and I have to buy lights and splitters weekly. She's only 2 weeks into flower and 4 and a half feet tall. I'm gonna have one big plant.
